Aquarium Glass Scraper with Printed Handle and Blade

I liked Chimore's aquarium glass scraper design, but wanted to add a printable handle for those who don't want to buy a wooden dowel, and a printable blade so it can be safely used on acrylic as well as glass.

I modified the blade holder and created the handle in PrusaSlicer. The negative volumes I used can't be exported, so I just uploaded the .3mf file. These parts were printed together in PLA without supports, 0.2 mm layers, and 15% gyroid infill. The handle fits into the blade holder quite tightly, so you can probably rely on friction to hold them together. You can also use glue or a screw the same size as those used to hold the blade. I just used some small screws I had laying around.

I created the blade in Fusion360. The edge of the blade is 0.5 mm thick. I printed the blade in PETG without supports, 0.1 mm layers, and 15% honeycomb infill.

Of course, you can still use a standard metal utility blade, as intended in Chimore's original design.

Added a 300 mm x 9.85 mm partially flattened rod to use as a handle for those who don't want to buy a wooden dowel for a handle. Added 3 mm diameter matching holes to the rod and blade holder so an appropriately sized screw or dowel, etc, can be used to secure the rod to the blade holder, although friction alone is probably sufficient in most cases and the parts can, of course, be glued together. Also designed a plastic blade for the scraper so it can be safely used on acrylic aquarium panels as well as glass.
